Gettleman actually put a good roster together for him, and Norvo was a much better game planner than his son. Besides Cam, he started off with Steve Smith and later Christian McCaffrey. It's like Fisher who managed to reach one SB because the GM landed McNair and Eddie George - as soon as he started handling personnel duties, he couldn't do anything with the average players he handpicked.
Snyder gave full personnel control to a coach who hadn't won a playoff game in over a decade; then the beloved one who had once traded 2 firsts for Desmond Howard, a 1and 3 for a washed up Gerald Riggs, and a future SB QB for a punter who got cut in camp; then it was to a coach who had won 1 playoff game in the last ten years, and finally Ron, who never had back to back winning seasons and only 3 winning seasons in 10 years.
